Particle system not to follow the GameObject?

Just a though if you are just rotating the particle on the Y axis then it may be doing what "you want it to do" but not how you want it to do it. You may have to send the particle out a bit on the up vector to make it spin not just rotate. Im just think out loud here. Hope that helps

     if (target) {
         x += Input.GetAxis("Mouse X") * xSpeed * 0.02;

         xSmooth = Mathf.SmoothDamp(xSmooth, x, xVelocity, smoothTime);
